My Passport for Mac weird behaviour

Could someone PLEASE explain me what the £^$%^ is going on with my passport for mac?

Occasionally it behaves like this: http://d.pr/i/Da7f

(not showing folder contents, size, this overload icon in ‘get info’)

gives me this when I eject it:  http://d.pr/i/why8 

only after a force eject it goes back to normal: http://d.pr/i/McsP

(displaying folder contents and size)

it still shows contents for the Downloads folder (torrent client accessing it all the time), but not all others. Really annoying. 

WD Drive Utilities Complete Drive Test passes, S.M.A.R.T. health is 99.4% (DriveDx)

I’ve had this drive for like 8months, during which it has given me 3-5 really loud and weird clicks, other than that no signs of failure.

I’ve had millions of WD drives over the years (no external ones for mac tho) and some of them have been clicking like an mmo lan party yet I’ve never seen anything like this, so I suspect it’s something software related - installing firmware upgrades and +turbo driver didn’t change anything however.

P.S. “Put harddisks to sleep” is alredy disabled in OS X. 

Please Help

Looks like some corruption in the links to files.

Some basic house keeping will probably cure.

The following  procedure for Macs takes 5 to 15 mins to undertake. I follow this procedure once a month.

Safe Boot Procedure:

Restart computer, holding down the SHIFT key until the blue screen appears.

This procedure rebuilds the directory.

Open Disk Utility, and Repair Permissions on the Boot Disk.

Restart computer.

(you will see in the Disk Utility pane that there are always links to files that are slightly damaged. You will see  DI do a repair job.)

Try this as a first possible cure, and report back, please.

Thanks for the advice. 

I have a bunch of uncorrectable permission errors, courtesy of latest itunes update, on startup disk, but what does it has to do with external drive behaving like that? 

P.S. verify disk in safe boot mode froze after 5min and I just couldn’t wait longer than 30min, yet it completed without error using disk utility on lion dvd, same my passport drive.

Hi

The reason I asked you to carry out the Safe Boot Procedure on your startup disk is that the well being of your startup disk  is the foundation stone for  your computers reliabilty.

The next step is to mount your external drive, and, using Disk Utility, select it, choose First Aid Tab, then click Verify Disk.

If all is OK you will see a listing of the checks made, and the statement “The Volume < disk name>  appears to be OK”.

Ensure “Show Dtails” is ticked.

If there are any problems listed choose “Repair Disk”

Any faults listed should now be corrected, and the report should reflect that.

The iTunes error permission errors are minor not important. Concentrate now on your external disk problem.

Hi, thanks

Luckily there are no errors on either

Right now it seems that external disk (or usb sleep) problem was caused by Energy Saver options - since I set computer sleep to “never” and unticked hdd sleep, the issue seems to have gone away 

That’s good.

the procedures I have described above, I would advise you to run through periodically. they help to keep your drives in good shape and reduce wear and tear.

it was caused by WD Security, which sometimes partially locks the drive when computer exits sleep mode
